As the buyer can very clearly see, if he could be bothered to look, that the price was incorrect. There really is no need to be quite so bolshy and unpleasant. I have blocked him as I only wish to deal with nice people that are sensible and not rude.
As the buyer can clearly see there was an error. Sadly he decided to take advantage to put me at a significant financial disadvantage. I do not wish to deal with people that are ready and willing to do this, it isn’t really in the spirit of either Delcampe, or the noble hobby of philately. Very disappointed in him so feel the only thing to do is block him and move in to my nice clients.
